8 Claims.

' This invention relates to window screens, and

moreparticularly to a novel screen for and in combination with a fenestral sash or other pivoted outwardly swingable window. I In sashes of this type swingably disposed within a suitable frame it is desirable that thescreen member therefore be maintained on the inside thereof to permit free outward movement of the sash.

Heretofore variousclosure operators or levers have been employed for opening and closing fenestral sashes or maintaining the same in any particular angular position with respect to the window frame.

Various types of closable openings have heretofore been employed within the screen for re ceiving said closure operators to permit manual regulation thereof.

This opening in the lower portion of the screen member also serves the further purpose of receiving a window latch or locking means and permitting entry of the hand for operating said latch which is secured to the lower portion of said sash for locking and unlocking the same with respect to a sill or stationary window frame when the swinging transom is located above the lower stationary window panels.

In each and every one of said devices it appears that some method or device was used for closing said opening when the window was opened in order to prevent the entry of insects, etc.

However, such openings when employed in factories and tool shops have been convenient for unfaithful employees in throwing out tools and other small equipment to be later picked up from the outside. Thousands of dollars are spent each year by manufacturers in replacing tools, etc., which are so disposed of.

In order to prevent these losses, the present invention embodies a novel lower screen element with the opening in the screen omitted and in its place substituting a pressed or otherwise suitably formed inwardly concaved recess for receiving the window latch as described hereinafter.

Consequently it is the purpose of this invention to provide the combination with the outwardly swingable fenestral window a suitable screen for receiving the window latch and the closure operator, and at the same time eliminating the opening heretofore provided for that purpose.

It is the further purpose hereof to provide a screen member through which the closure operator is slidable and through which the fingers of an individual may beinserted for actuating the window locking latch. The invention relates to the various elements and combinations thereof hereinaftervset out in detail in connection with the appended drawing of which: 1 i

Figure 1 is a sectional side'elevational View of the screen and fenestral window.

Figure 2 is a front elevational view thereof from the inside. W It is to be understood that the particular arrangement of elements illustrated and described herein is'merely the preferable embodiment of the invention by way, of example,.as it is not the purpose of the inventor to limit the invention thereby. v v In the drawing the frame has horizontally pivoted atll2 therein the fenestral sash l3 with the glass members I4. The lower sectionof said sash is adapted to swing outwardly'upon said pivots with its upper portion swinging inwardly; and is adapted for adjustment ina plurality of angular positions with respect to said frame.

The screening for said window consistsof an upper screen or other suitable wire mesh l5 fixedly retained andsupported by the moulding or bars 16 within frame H on the outside of sash 13.. 1-

The lower section of screen or wire mesh [1 supported within moulding I8 is disposed vertically within frame ll upon the inside of the sash'l3, whereby the latter is free to swing outwardly with respectv to ,a. sill member, 19. In applicants preferable" embodiment the lower screen section" li'isf provided with a centrally disposed inwardly concaved recess'20 formed therein. It will be noted that said recess may be formed in any one of a plurality of ways such as, by pressing, or assembling.

The lower portion of the sash i3 has pivotally secured thereto a closure operator arm 2| provided with a plurality of notches 22 in the lower surface thereof for selective cooperating engagement with the sill member IQ for maintaining sash 13 in any desired angular position with respect to frame I I.

It will be noted that the closure operator 2| is adapted for entry through screen member I! thereby permitting angular adjustment of said window.

A latch member 23 is also pivoted to the lower portion of sash l3 adjacent the pivotable connection of the closure operator arm for locking and unlocking said sash l3 with respect to sill [9.

The concave recess 20 within screen member I! is adapted to receive said latch whereby the same may bemanually or mechanically opened or closed by the insertion of ones fingers or bars through the wire mesh adjacent said recess 20.

By the provision of said recess 20 it is seen that no opening is necessary within screen member I1; and by eliminating said opening it is impossible for an employee to throw out tools or equipment to be later picked up.

Consequently, it Will be seen that by the provision of said recess which may be disposed in any convenient position the objects heretofore set out are accomplished.

It is also included as within the scope of this invention that such a pivotal window sash may be operated in the combination without theuse of the arm or lever 2|, though the same is desirable.

Furthermore it will be seen that the invention includes a window sash which merely swings outwardly from either its top or bottom. That is, the combination is equally applicable even though no portion of the sash is swingable inwardly.

It. will be further noted that the invention is equally adaptable to a vertically hinged or pivoted window with the recessed screen member on the inside thereof.

Having described the invention in detail, reference should now be had to the claims which follow for determining the scope of my invention:

I claim:

1. In a screen for a window sash pivotally mounted in a frame, a screen one portion of which is mounted inside the face of said frame adjacent the upper half of said window on the outside thereof, and the other portion is secured inside the face of said frame adjacent the lower half of said window on the inside thereof, said lower portion being provided with an inwardly bulged portion forming a recess, a window actuating lever joined to said sash, adapted for entry through said screen, and a latch pivoted to said sash adapted to be nested within said recess in closed position of said sash.

2. In a screen for a horizontally pivotal sash mounted in a frame, a wire mesh inside the face of said frame adjacent the upper half of said sash on the outside thereof, a wire mesh inside the face of said frame adjacent the lower half of said sash on the inside thereof, being provided with an inwardly bulged portion forming a recess, an actuating lever joining said sash adapted for entry through said mesh, and a latch secured to said sash adapted to be nested within said recess in closed position of said sash.
